Problems related to the measurement of high current lightning pulse in a noisy environment are investigated, to improve the Data Acquisition System of Morgan Botti Lightning Laboratory. A transducer based on Rogowski coil and passive RC integrator is tested. Solutions are proposed to enhance SNR, including numerical and electronic filtering.

Abstract

Problems related to the measurement of high current lightning pulse in a noisy environment are investigated, to improve the Data Acquisition System of Morgan Botti Lightning Laboratory. A transducer based on Rogowski coil and passive RC integrator is tested. Solutions are proposed to enhance SNR, including numerical and electronic filtering. Results show that measurements are affected by type of coil used, its position in the circuit and by an initial disturb. Hypothesis on its origin are made
